"Mackynzie and Michael are thrilled to welcome a little brother, and we are so thankful that mom and baby are well," Josh and Anna told the Today show's website. "We are blessed to have our family close as we celebrate this gift from God!"

The 19 Kids and Counting stars married in 2008. They've previously expressed their desire to leave the size of their family up to God, and they're not ruling out having lots of children like Jim Bob and Michelle.

"It's really not about the number of children you have," Josh, 25, told E! News previously, "but how well are you doing with the children that God has given you. We're really just going to take it one at a time. I don't think you can say we're going to set out and say we're going to have five kids or four or three. We have no control over that. God has the control."

He added: "Obviously, we can do things to prevent that, but I'm glad my parents didn't just settle to have three or four children. There are definitely a lot of advantages to trusting [in God]. Anna's glad that her parents didn't stop at four, because she was number five."

But that's not the only way Josh and Michelle will be following in Jim Bob and Michelle's footsteps. They will also be documenting the birth of their bundle of joy on 19 Kids and Counting: GrandDuggar Makes 3!, which airs on TLC on Father's Day.
